EJECTOR FOR SIDE-SEAIVIING MACHINES.

SPECIFICATION forming part f Letters Patent No. 734,759, dated July 28, 1903. l

` Application led January 19, 1903. Serial No. 139,540. (No model.)

a No. 585,635, dated June 29, 1897; and it con- Vzo sists in improvements in the mechanism for operating the ejectors and also in the form and construction of the ejectors, adapting them to be used in making cans of diiferent diameters.

In the drawings annexed to this specifica'- tion, Figure l is a side view of the entire seaming-machine with the mechanism for operating the ejectors. Fig. 2 is a detail showing a part of the mechanism for giving reciprocating motion to the ejectors. Fig. 3 isa detail of ejector-cam and cam-rod. Fig. 4 is a crosssection of the ejector-rods and mechanism connected therewith. Fig. 5 is an end view of the ejector and the can-carrying mandrel.

The seaming-machine illustrated in Fig. l is fully described in the speciiicationforming a part of application for Letters Patent led by me February 12, 1901, and subsequently divided as required by the Commissioner of Patents. It consists, substantially, in mechanism for forming the cylindrical portion of a tin can by wrapping a sheet of tin of suitable size and form around a cylindrical mandrel projecting from the face of the machine and joining thev edges of. the blank by folding and soldering them and mechanism forpushing the completed cylinder from the mandrel after the seam is thus formed.

As the invention claimed in the present application relates only to the ejecting mechanism, only that portion of the machine is now specifically described.

A is the base of the machine, upon which is the column A', upon which is mounted the greater part of the operating mechanism.

A6 is a shaft supported by the4 column A short shaft jonrnaled in the standard A4.

Q5 isa link carrying a shoulder-stud Q6, which works in the slot of the arm Q4 and connecting the arm Q4 with the lever Q6, pivoted Y to the base A of the machine.

Y Q7 is a guide-roll mounted on a pin projecting from the standard A4 and acting to hold the rack Q2 in engagement with the segmentgear Q3.

The position of the shoulderestud Q8 on the arm Q5 is made adjustable, thereby regulating the extent of movement of the lever Q6 and adapting the ejector to cans of different lengths.

QJ is a cross-head sliding` upon the guide Q12.

Q11 Q11 are ejector-rods adjustably secured to the cross-head Q12 and passing through the column A,Vone on each side of the mandrel b.

Q13 is acleat secured to the cross-head QJ and holding the same in contact with the guide Q12.

Q14 is a pin and roller on a projecting ear of the cross-head Q9 and engaged by a slot in the lever Q6.

Q16 is a pivot on which the lever Q6 works.

Upon the ends of the ejectorrods Q11 are arms Q11, terminating in circular projections Q16 Q16, iitting in corresponding grooves in the sides of the mandrel b. The operation of the cam Q is so timed that the ejector-rods are drawn back before the formation of the canbody commences, and during the making of the seam the projections Q16 lie behind and in Contact with the rear edge of the can-body. After the operation of forming the seam is completed the ej ector-rods move forward and the projections Q16 push the can-body off from the mandrel.

The ejector-rods Q11 are so placed in relation to the mandrel o that the are described by the projections Q16 when moved about the center of the ejector-rod will intersect the surface of the mandrel b nearly at the intersection of its horizontal diameter with its surface, and the grooves in the sleeve b', which is placed over the mandrel b When cans of ya size larger than the mandrel are to be made, are so located as also to intersect this arc, so that one pair of ejectors may serve to eject cans of all sizes Within the capacity of the machine.

What I claim as my invention, and desire to secure by Letters Patent, is

l. In a machine of the class described having ejector-rods gu mounted upon a sliding cross-head operated by a lever Q6 means for giving said lever oscillating motion, consisting of the rack g2 to which vertical reciprocating motion is given by means of the cam g and cam-rod g, segment-gear g3 engaging said rack, slotted arm glo rigidly attached to the shaft on which said segment-gear is mounted and link g5 pivoted at one end to the lever gG and at the other end carrying a shoulder-stud g8 Working in the slot of the arm g10 substantially as described. v

2. In a machine of the class described, in combination With a grooved can-forming mandrel b having removable grooved sleeves adapted to cans of different sizes, ejectorrods g11 situated on opposite sides of the mandrel, means for giving said ejector-rods reciprocating rectilinear motion, adjustable arms g" attached to said ejector-rods and terminating in projections 916 adapted to slide in grooves in the sides of said mandrel and sleeves, said arms Q17 being adjustable in a plane at a right angle `with the axes of said ejector-rods to conform to the varying diameter of the mandrel-sleeves, substantially as described.
